Microsoft's Xbox 360 E3 keynote video is now available for replays online

The pre-E3 briefing is crucial for all major videogame companies, and if you missed Microsoft's noontime keynote yesterday you can relive it live and in HD on Xbox.com. The stream is up on Xbox.com for your viewing pleasure to be shocked (again) that Call of Duty: Black Ops 2 and Halo 4 are going to involve shooting things, or marvel at how much time Microsoft spent highlighting the Xbox 360's non-gaming prowess with fitness or video applications. Check in with Major Nelson and the crew at the source link below, although we're sure it could use some SmartGlass tie-ins with our liveblog coverage.
